My invention relates to a circumrotary riding device. 7 c.

The ob ect of my 1nvent1on 1s to provide a circumrotary riding device comprising a platform rotatably mounted ona vertical shaft and being rotatable by reason of chains connected toan offset portion of the shaft. A further object of my invention is to provide a removable securing means for; the

hood.

A. still further object of my invention is to provide a differently positioned angle for the eccentrically positioned stationary crank.

'A stillfurther object of my invention is to provide a sleeve on the center post to avoid raising of the intermediate ends of the platform timbers, and also to show simplicity of construction for the liorizontal' sup'port of the platform timbers and connecting means for the railingto the timbers. A still further object of my invention is to provide a removable means for the panels of the conical portion of the structure, terminat ing at the inside of the annular platform, and also means by which one or more of the panels may be removed.

These and other objects will hereinafter be more fully explained, reference beingh ad to the accompanying drawings forming part of this specification, wherein like characters will apply to' like parts throughout the different views.

Referring to the drawings :1 Fig. 1 is an elevation of the machine, partly in section,taken along line 1 in Fig. 2.

Fig. 2 is a plan view, partsremoved' for I convenience .of illustration;

Fig. 3 is an enlarged sectional .vi on line 3-3 in Fig.1. 7 7 g Fig. 4 is a fragmentary plan view of one of the standards, carrying rod, and beam;

The invention herein disclosed consists of a frusto-conical hood 1 having an aperture at the frustum end toengage over'the center 45* post 2. The opposite or lower; end of the P hood rests snugly on the panels 3, which function as an enclosure and form a conical l body extending from the annular platform 4 and terminating near the center post, as shown in Fig. 1. r

ew taken RIDING DEVICE 1923. Serial 110,296,025.

In Fig. 2 is shown a panel 3 removably arranged, the said panel having a plate 5 securely attached thereto by means of screws 6; the ends of the plate lap well onto the adjacent panel on each side, and areattached' thereto by scrcw's 7, the plate being of sufficient width to extend well under the conical hood, as shown by dotted lines A, the opposite side being'eXposed'as accessible means to the said screws. All other panels are attached by a plate 8, as shown in Fig. 2, said plate secured to'the adjacent panels by means of screws 9. The opposite end of the panels fit snugly against the inner edge of the annular platform and against the standards 10, by which means the lower ends of the panels cannot be raised until the upper ends'have been released by the removal of their respective screws. The intermediate edge portions of the panels are carried by a U-shaped cleat 11, the sides of the cleat fitting snugly on the carrying rods 12; the sides of the cleat extend outward as at B, functioning as a bearing for the edges of the panels as shown in Fig. 3, the panels. loosely engagingthereon. The lower ends of the rods 12 extend downward and are: bent obliquely to extend through an aperture 13 in the right angle bent end C of'the standard, and through an aperture in registry therewith in the beam 14, and being secured by a nut 15 at the lower end thereof, by which means the railing 16 secured to the said beam simultaneously, and

simultaneously supporting the beams in horizontal alignment. It will be understood that the upper ends of the rodsf12 are securely attached to a plate 12, said plate-bearing on the upper portion of a ball bearing and rotatable therewith, the lower portion of the hearing being rigidly attached to the post, by which means the structure is rotatably arranged; and to avoid rocking, the beams radially extend from the center post, and the inner ends thereof are secured to a plate 14, the said plate being apertured to revolve freely on the center post. I havealso placed a collar to engage firmly on the said post as a means to prevent downward movement of the inner ends of the beams. As a means to prevent-upward movement'of the inner ends of the beams, a sleeve 2 is placed on the center post, and being of suflicient length to e tend from the beam members to the under side of the ball bearing.

As a means to prevent the removal of the conical hood, I have placed a collar 1.7 threadedly engaging on the upper end of the post.

he said collar also functions a lQ-QllfOiCQw ment for the apertured end of the post, which provides a seat for the eccentrically positioned stationary crank 18, it being under- 7 stood that considerable strain is placed on the crank when the machine is being rotated. It will also be understood that the collar does not bind snugly on the frustum end of the hood, but is merely in close proximity thereto. so that the hood is free to revolve with the body of the machine.

In this application I have shown a crank 18, which is rigidly attached to the center post 2;, the said crank having a lateral bend as at D to, a vertical portion, on the outer end of which is positioned a disolike meniber 19 rotatably engaging thereon as pendent supporting means for a plurality of chains or cords 20, functioning as pulling means by occupants to rotate the machine. all of which was disclosed by my former application, hereinbefore referred to. However, in the former application, the lateral bend referred to is positioned in parallelism with the conical form; but it is found that by raising this portion of the crank as herein set forth. all danger of being wedged between the bend and the cone is eliminated.

It will be understood that the collar and hood, as removed, are free to follow the curvature of the crank by removing the disc member 19, and by moving disc 19. This arrangement eliminates the removal of the crank when the bearing is to be investigated for repair or oiling, and other accessible means is the panel heretofore referred to, in which case workmen can enter without difficulty.

Such modifications may be employed with reference to varying the curvature of the crank, or the extent and pitch of the conical hood without departure from the spirit of the invention; and such other modifications may be employed as lie within the scope of the appended claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a circumrotary riding device, a structure of the kind described comprising an annular platform, a frustoconical portion, a vertical center post, standards and railing on the platform, the frusto-conical portion intermediately positioned-to the platform and upwardly extending, and the center post functioning. as positioning means around which the platform and conical portion revolve, a plurality of rods radially positioned and in parallelism with the conical portion, the lower or outer ends of the rods attached near the inner peripheral edge of the platform to carry the same and simultaneously attach the railing standards, a plate carried by a ball bearing, the ball bearing positioned on the center post and rotatable thereto, the opposite or inner ends of the rods attached to the plate, a conical hood positioned on the frustum end of the first said conical. portion, the upper end of the hood being apertured to revolve on the post, and a collar threadedly engaging on the upper end of the post as securing means for the hood against removal, the hood rotatable with the first said conical portion and functioning as a closing means for the top.
